Jewish Calendar
The Hebrew calendar (), also called the Jewish calendar, is a lunisolar calendar used today for Jewish religious observance and as an official calendar of Israel. It determines the dates of Jewish holidays and other rituals, such as ''yahrzeits'' and the schedule of Weekly Torah portion, public Torah readings. In Israel, it is used for religious purposes, provides a time frame for agriculture, and is an official calendar for civil holidays alongside the Gregorian calendar. Like other lunisolar calendars, the Hebrew calendar consists of months of 29 or 30 days which begin and end at approximately the time of the new moon. As Lunar calendar, 12 such months comprise a total of just 354 days, an Intercalation (timekeeping), extra lunar month is added every 2 or 3 years so that the long-term average year length closely approximates the actual length of the solar year. Originally, the beginning of each month was determined based on physical observation of a new moon, while the decisi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jewish Calendar, Showing Adar II Between 1927 And 1948
Jews (, , ), or the Jewish people, are an ethnoreligious group and nation, originating from the Israelites of History of ancient Israel and Judah, ancient Israel and Judah. They also traditionally adhere to Judaism. Jewish ethnicity, religion, and community are highly interrelated, as Judaism is their ethnic religion, though it is not practiced by all ethnic Jews. Despite this, religious Jews regard Gerim, converts to Judaism as members of the Jewish nation, pursuant to the Conversion to Judaism, long-standing conversion process. The Israelites emerged from the pre-existing Canaanite peoples to establish Kingdom of Israel (Samaria), Israel and Kingdom of Judah, Judah in the Southern Levant during the Iron Age.John Day (Old Testament scholar), John Day (2005), ''In Search of Pre-Exilic Israel'', Bloomsbury Publishing, pp. 47.5 [48] 'In this sense, the emergence of ancient Israel is viewed not as the cause of the demise of Canaanite culture but as its upshot'.

Zmanim
''Zmanim'' (, literally means "times", singular ''zman'') are specific times of the day mentioned in Jewish law. These times appear in various contexts: Shabbat and Jewish holidays begin and end at specific times in the evening, while some rituals must be performed during the day or the night, or during specific hours of the day or night. Calculations Relative hours The daytime period is divided into twelve equal "relative hours" (or "seasonal" or "variable" hours), which can be longer or shorter than 60 minutes, as the period of daylight is generally not exactly twelve hours long. Hours of the day are counted according to these relative hours for commandments: thus, the Shema prayer must be recited in "the first three hours" of the day, i.e., the first 1/4 of the daytime period. There are two major opinions regarding the definition of the daytime period: *According to Magen Avraham the period between ''daybreak and nightfall'' is divided into 12 hours. Usually this time is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Noon
Noon (also known as noontime or midday) is 12 o'clock in the daytime. It is written as 12 noon, 12:00 m. (for '' meridiem'', literally 12:00 midday), 12 p.m. (for ''post meridiem'', literally "after midday"), 12 pm, or 12:00 (using a 24-hour clock) or 1200 ( military time). Solar noon is the time when the Sun appears to contact the local celestial meridian. This is when the Sun reaches its apparent highest point in the sky, at 12 noon apparent solar time and can be observed using a sundial. The local or clock time of solar noon depends on the date, longitude, and time zone, with Daylight Saving Time tending to place solar noon closer to 1:00pm. Etymology The word ''noon'' is derived from Latin ''nona hora'', the ninth canonical hour of the day, in reference to the Western Christian liturgical term Nones (liturgy), (number nine), one of the seven fixed prayer times in traditional Christian denominations. The Roman and Western European medieval monastic day began at 6:00& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relative Hour
Relative hour (Hebrew singular: / ; plural: / ), sometimes called halachic hour, temporal hour, seasonal hour and variable hour, is a term used in rabbinic Jewish law that assigns 12 hours to each day and 12 hours to each night, all throughout the year. A relative hour has no fixed length in absolute time, but changes with the length of daylight each day - depending on summer (when the days are long and the nights are short), and in winter (when the days are short and the nights are long). Even so, in all seasons a day is always divided into 12 hours, and a night is always divided into 12 hours, which invariably makes for a longer hour or a shorter hour. At Mediterranean latitude, one hour can be about 45 minutes at the winter solstice, and 75 minutes at summer solstice. All of the hours mentioned by the Sages in either the Mishnah or Talmud, or in other rabbinic writings, refer strictly to relative hours. Another feature of this ancient practice is that, unlike the standard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molad
''Molad'' (מולד, plural ''Moladot'', מולדות) is a Hebrew word meaning "birth" that also generically refers to the time at which the New Moon is "born". The word is ambiguous, however, because depending on the context, it could refer to the actual or mean astronomical lunar conjunction (calculated by a specified method, for a specified time zone), or the ''molad'' of the traditional Hebrew calendar (or another specified calendar), or at a specified locale the first visibility of the new lunar crescent after a lunar conjunction. Other than its usage connected with the lunar cycle, ''מולד'' is also the word used in the Hebrew term for Christmas, ''חג המולד'' (literally "Holiday of the Birth" or "Holiday of the Nativity"). The traditional ''molad'' interval The ''average molad'' (), which is used for the traditional Hebrew calendar, is based on a constant interval cycle that is widely but incorrectly regarded as an approximation of the time in Jerusalem of the mea ...

Helek
The helek, also spelled chelek (Hebrew חלק, meaning "portion", plural ''halakim'' חלקים) is a unit of time used in the calculation of the Molad. Other spellings used are ''chelak'' and ''chelek'', both with plural ''chalakim''. An hour is divided into 1080 halakim. A helek is 3 seconds or 1/18 minute. The ''helek'' derives from a small Babylonian time period called a ''she'', meaning '"barleycorn", itself equal to 1/72 of a Babylonian time degree (1° of celestial rotation). :360 degrees × 72 ''shes'' per degree / 24 hours = 1080 ''shes'' per hour.

Biblical And Talmudic Units Of Measurement
Biblical and Talmudic units of measurement were used primarily by ancient Israelites and appear frequently within the Hebrew Bible as well as in later rabbinic writings, such as the Mishnah and Talmud. These units of measurement continue to be used in functions regulating Orthodox Jewish contemporary life, based on halacha. The specificity of some of the units used and which are encompassed under these systems of measurement (whether in linear distance, weight or volume of capacity) have given rise, in some instances, to disputes, owing to the discontinuation of their Hebrew names and their replacement by other names in modern usage. Note: The listed measurements of this system range from the lowest to highest acceptable halakhic value, in terms of conversion to and from contemporary systems of measurement. Unit conversion Archaeological While documentation on each unit's relation to another's is plentiful, there is much debate, both within Judaism and in Jewish studies, academia ...

International Date Line In Judaism
The international date lineThe convention used is to capitalize "Date Line" (or "International Date Line") when it refers to the ''standard'' International Date Line, but to use small letters to refer to possible construct(s) under Jewish law. in Judaism is used to demarcate the change of one calendar day to the next in the Jewish calendar. It is not necessarily the same as the internationally recognised International Date Line (IDL - which is 180° from the Greenwich Meridian, passing through London, UK). On the east side of the IDL it is one day, on the west side it is the next. However, the conventional International Date Line is a relatively recent geographic and political construct whose exact location has moved from time to time depending on the needs of different interested parties. While it is well-understood why the conventional date line is located in the Pacific Ocean, there are not really objective criteria for its exact placement within the Pacific. In that light, it ...

International Date Line
The International Date Line (IDL) is the line extending between the South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180.0° line of longitude and deviating to pass around some territories and island groups. Crossing the date line eastbound decreases the date by one day, while crossing the date line westbound increases the date. The line is a cartographic convention and is not defined by international law. This has made it difficult for cartographers to agree on its precise course and has allowed countries through whose waters it passes to move it at times for their convenience. Geography Circumnavigating the globe People traveling westward around the world must set their clocks: *Back by one hour for every 15° of longitude crossed, and *Forward by 24 hours upon crossing the International Date Line. People traveling eastward must set their clocks: *Forward by one hour for e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halakha
''Halakha'' ( ; , ), also Romanization of Hebrew, transliterated as ''halacha'', ''halakhah'', and ''halocho'' ( ), is the collective body of Judaism, Jewish religious laws that are derived from the Torah, Written and Oral Torah. ''Halakha'' is based on biblical commandments (''Mitzvah, mitzvot''), subsequent Talmudic and Mitzvah#Rabbinic mitzvot, rabbinic laws, and the customs and traditions which were compiled in the many books such as the ''Shulchan Aruch'' or ''Mishneh Torah''. ''Halakha'' is often translated as "Jewish law", although a more literal translation might be "the way to behave" or "the way of walking". The word is derived from the Semitic root, root, which means "to behave" (also "to go" or "to walk"). ''Halakha'' not only guides religious practices and beliefs; it also guides numerous aspects of day-to-day life. Historically, widespread observance of the laws of the Torah is first in evidence beginning in the second century BCE, and some say that the first evide ...

Shabbat
Shabbat (, , or ; , , ) or the Sabbath (), also called Shabbos (, ) by Ashkenazi Hebrew, Ashkenazim, is Judaism's day of rest on the seventh day of the seven-day week, week—i.e., Friday prayer, Friday–Saturday. On this day, religious Jews remember the biblical stories describing the Genesis creation narrative, creation of the heaven and earth in six days and the redemption from slavery and the Exodus from Egypt. Since the Hebrew calendar, Jewish religious calendar counts days from sunset to sunset, Shabbat begins in the evening of what on the civil calendar is Friday. Shabbat observance entails refraining from 39 Melachot, work activities, often with shomer Shabbat, great rigor, and engaging in restful activities to honor the day. Judaism's traditional position is that the unbroken seventh-day Shabbat originated among the Jewish people, as their first and most sacred institution. Variations upon Shabbat are widespread in Judaism and, with adaptations, throughout the Abraham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
